Specification of Letters Patent.

Patented A11 8, 1916.

Application filed July 22, 1915. Serial No. 41,248.

To all whom it may concern:

Be it known that I, Fnuxxnn BoYER, immufacturer, a citizen of the Republic of France. residing at Paris. in the Republic of France, have invented certain new and useful Improvements in Attachments to (arpet-Knotting Machines for Shooting In the Filling, of which the following is a specification.

The present invention relates to an attaclnnent for shooting in the filling in carpet knotting machines where the knots are made on vertically running warps. and comprises means for forming a shed above a row of knots immediately after the same have been tied, means for guiding a shuttle and means for moving a reed.

The annexed drawing represents two working examples of the invention, and for sake of plainness, the means for knotting are not shown.

Figures 1 to 7 illustrate one form with lower movable guide of the shuttle. Fig. is a diagrammatic side ele 'ation. Figs. and 3 are partial front views. Figs. 1, and 6 are views of details in different positions. Fig. '7 is a partial front view of a detail. Figs. 8 and 9 are diagrammatic views of the backing fabric. Figs. 10, 11 and 12 relate to a second form. without a lower, movable guide for the shuttle. Fig. 10 is an end view of the shuttle. Fig. 11 a partial side elevation. Fig. 12 a partial front view of the means for guiding the shuttle and for moving the reed. Fig. 13 is a par tial elevation and cross section on an enlarged scale illustrating the construction of the mechanism by which the reed is shifted out of its normal position during predetermined operations of the machine. Fig. 11 is an elevation and partial cross section of the reed, its frame, and associated parts taken at right angles to the position of these parts as shown in Fig. 13. Fig. 15 is a sectional plan on the line 1, 1. Fig. 13, and Fig. 1G is a partial elevation similar to Fig. 13, showing the reed. its frame and associated parts in their shifted positions.

Referring to Figs. 1 to 7, a frame 1 is provided at each side of the machine and supports the bearings for all the shafts and lever arms. \Varp w unrolling from a warp beam 30 mounted outside of the machine, is guided over a lathe 31 and beam 32 toward the reed 23 and is furnished at 1] (Fig. 5) with the filling and with knots so as to form a carpet. Thence the finished carpet runs over a roller 33 on a shaft 35 to a beam 31 outside of the machine, where it is rolled up.

The means for shooting in the filling, for moving the reed and for forming the shed, and the means for guiding the shuttle, are actuated from shaft 2, there being a cam disk 3 keyed thereon and provided. with grooves for guiding the parts for moving the reed and the lower guides of the shuttle. The reed 23 is provided with guide members for directing the path of the warp thread, the reed 23 being mounted between two frames 24:, the ends of which are secured by means of bolts 25 to links 22. These links are hinged to a rod 21 which connects two arms 20 keyed to a shaft 15 and are given a vertical rocking movement from an angular lever 13, 11. by means of an arm 16 fast on a shaft 15, and by means of a connecting rod 17 which is provided at its ends with link connections 18, 19. The angular lever 13, 1-1, receives a rocking movement from a cam disk 3 on shaft 2. A curved groove in said disk guides a cam roller provided at the end of an arm at keyed to the same shaft 5 where is keyed also an arm 6. This arm is hinged at its end to a rod 7, said rod engaging with a hook a pin held by the forked end of the arm 13 of angular lever 13, 11.

In order that the movement and travel of the reed may be accurate the links 22 carrying the reed 23 and reed frames 21 are guided sidewise by friction rollers 29 running in guide bars 28 normally maintained in a vertical position. These guide bars 28 are pivotally connected by a pin 28 in the extremity of a strut 27 connected to and depending from a girder 26 which is supported by and extends between the frame members 1. The strut 27 is braced by auxiliary struts 27 extending from thelower end of the strut 27 to the frame members 1. The guide bars 28 are connected to the cam disk 1 through an adjustable connecting rod e. a bell crank lever 7', g, a link It, and a bell crank lever i, It. These parts are operated just prior to the time when the knotting process takes place, that is, when the pile threads are tied around the warps, so as to swing the reed and the frames carrying the same from their normal positions as shown in Fig. 13 to the positions these parts assume during the knotting process as indicated in Fig. 16, in order that these parts may not interfere with the operation of the knotting mechanism. After this by the same link and lever mechanism the guide bars are returned to their normal vertical positions in order that when the links 22 are reciprocated a vertical reciprocating movement or travel may be imparted to the reed and the frames carrying the same.

The connecting rod 7 may be hooked into or out of engagement with the angular lever 12- 1+, whenever the reed has to be moved or to be set at rest. Said rod however is worked in connection with a rod (1. which is actuated from a shaft for imparting movement to the knotting tools and for moving the reed in connection therewith, as shown and described in my copending application Serial X0. 804.221. filed September 30th. 1911.

Rods u and 7 are guided near their hooked ends within slots and between friction rollers b 8, provided on two parallel links 9. 10, said links forming with the two armed lever 12 and two arms of a three armed lever 11, a

.hinged frame shaped like a lmrallelogram which is worked by the third arm of lever 11 in such a way that if either one of the rods is disconnected from the 'pin on th arm 13 the other rod will be connected thereto.

In order to obtain a backing fabric as is represented in Figs. 8 and 9, a woof thread .2' has to be shot into the warp a". and to do this a shuttle-box 2-56 is attached to the outside of each frame. A shuttle 3? is indicated in Figs. 2 and 3. The woof thread runs from a spool 38 inside the shuttle (Figs. 7, 1t), and 12) across the bottom of-the body of the shuttle to its outside. For forming the shed. each warp thread m runs through the eye of a heddle 3i). which heddles are arranged horizontally in two horizontal rows. an upper and a lower row. at the rear of the warps, and are held fast within two flat straight bars 40 (Figs. 1. 4 and (3) attached at right angles rigidly to theends of the horizontal slide bars 41 which are guided within brackets 42 (Figs. 1 and 3). fast to a cross beam 43 connecting the frames 1. The slide bars 41 are provided with racks -14: which engage pinions 45 one of the same being on each side of the machine and keyed to a shaft 46 running through the whole machine. These pinions being placed each between an upper and a lower bar arc adapted to move bars simultaneously but in opposite directions. The shaft 16 is journaled in the brackets 42 within the side frames 1 and projects at one end outside the frame. At one endexteriorly of the frame. the shaft 16 carries a pinion 47engaging a toothed segment -18 journaled on'a pin 49 fast to the frame. An oscillating movement is imparted to the segment 48 from the driving shaft 2 by means of a set of spur wheels 51, and a two armed lever 55, 56, which is journaled on apin 51 fast in the frame, one arm of said lever being connected by a rod 57 to a forked arm 50 of the segment, while its other arm is fitted with a friction roller and is, guided thereby in a groove on one side face of the spur wheel 52, which is journaled to a pin 53 supported between a bracket and the side frame. 'hen the driving shaft 2 turns, the lever 56. will be oscillated and this movement will also be imparted to the segment 18 and to pinions r?) and thereby the bars all and the needles 3!) will be caused to reciprocate. the upper bars advancing. while the lower are retreating, and vice versa. The warp threads :r therefore which alternately run through an upper and through a lower heddle will be swung as indicated in Fig. -1 part into a position m and part into a position w. which positions will be reversed into a position as indicated in Fig. 5, and again into the position of Fig. 4, for each oscillation of the pinions l5. and sheds will thus be formed for shooting in the filling or the woof. To this end the shuttle box 36 is fitted with a shuttle driver 58 made of suitable material, as for instance of leather, which in its starting position bears against the shuttle 37 (Fig. 2) and is engaged through a slot by the upper end of a picking stick 55), the lower end of which is held fast within a picking. lever- (30. This latter is rigidly fixed on a pin (31 journaled within a bracket (32 attached to the frame 1 aml is adapted to be pulled back again after each throw of the shuttle into the position illustrated in Fig. 2, by means of a spring not shown in the drawing. but which is attached to the. pin (33 at the lower end of said lever. \Vithin the same bracket (32 another pin 61 is journaled somewhat behind the pin 61 and projects to-the right side of said bracket, as viewed in Fig. 1. where it is also journaled in an auxiliary bracket arm 65. This pin (9+ carries at its projecting end and set crosswise a pin with journaled roller (56 and be tween the two arms of the bracket 62 a downwardly set forked lever 67 (F igs; l and 3). Journaled roller 06 in the starting position bears against the hub of a wiper 68 which is rigidly fast to the shaft (39 running along the whole machine and driven in the direction of the arrow in Fig. 1 from the driving shaft 2 by a gear not shown in" the drawing. At each end of this shaft and on both sides of the machine such a wiper 68 is provided, but the two are set at an angle of 180 to each other.

Opposite to the bracket 62 on the inside of the frame 1 a bracket 70 is bolted fast to the frame with bearings for a shaft 71 (Figs. 1 and 3) and two arms are keyed on to this shaft. a downwardly set arm 72 fitted With a sharp edge and an upwardly set arm 73 fitted with a clutch for clamping a belt 74 connecting said arm to the picking-lever (3O and fitted also with a stop resting therewith against an adjustable stop bolt 76 owing to the springy pull exerted in the direction of the arrow in Fig. 3, by the retreated picking lever 60. A rod 77 kept in constant contact with the sharp edge at the end of the arm 72 owing to the pull of a spring 79 which connects the one end of said rod with a stud fast to bracket 70 is linked with its other end to the forked part of lever 67 and engages with a shoulder 78 the sharp edge of arm 72. On the end of the link bolt where lever 67 meets rod 77 there "is also provided a knob 80 which is attached to the frame by a spring not shown in the drawing, for the purpose of maintaining a constant pull on lever 67 toward the frame.

\Vhenever the shaft 69 is turned in the direction of the arrow, the wiper 68 will lift roller 66 which will cause lever 67 to swing outwardly together with rod 77. Shoulder 78 which when at rest is at some distance from the sharp edge of arm 72 will strike against it (Fig. 3) and will swing arm 73 so as to give a short pull on belt 7 L whereby picking lever 60 and picking stick 59 will be caused to strike rapidly in the direction of the arrow in Fig. 3, sending the shuttle 37 through the shed which has been opened in this very moment and sending it farther into the opposite shuttle box 36, where a similar action takes place owing to the wiper 68 set at an angle differing by 180, from the direction of the first wiper. After each stroke the picking stick 59 will again assume the starting position according to Fig. 3, but only during the intervals between the engagements between roller 66 and wiper 68.

In order to produce a suflicient velocity of the shuttle, the shaft 69 has toturn ratherrapidly and then too little time may be left to the shuttle 37 for its movement because the wipers set at an angle of 180 from each other would move the opposite picking sticks before the shuttle will have reached the shuttle driver 58 at the outer end of the shuttle box. An interrupting device has therefore been provided which brings shoulder 78 some times out of thepath of the sharp edge of arm 72. This may be done by the two armed lever 82, S3, pivoted ona pin 81 fast to theinside of the frame. Arm 82 of this lever rests above rod 77 (Figs. 1, 2 and 3) and arm 83 is linked by a rod 86 to an arm pivoted on a pin 84 fast to the frame and fitted at its middle part with a sliding piece 87 (Fig. 1). An arm 85 rests by means of this sliding piece on a curve 88 provided on the hub of gear wheel 52 which turns in the direction of the arrow indicated thereon and will therefore allow the engagement of the shoulder 78 with thesharp edge of the arm 72 and thereby also the throw of the shuttle only durinq the moments when sliding piece 87 has sun into the hollow of said curve 88 (Fig. 1). At any other moment arm 85 will be lifted again and thereby arm 82 will be caused to throw shoulder 78 out of the path of the sharp edge of arm 72. All these operations are very similar to the usual weaving operations. In the present case however the difference exists in the lower guiding means of the shuttle. In the ordinary looms the warp runs horizontally and the shuttle moves on a lathe which supports the same even during the travel. Here such a stationary lathe is impossible because the filling 2 has to be beaten up against the finished part (Figs. a

and 5) at y. Therefore movable battens have been provided which support the shuttle and are withdrawn again therefrom at suitable moments. Small guide plates 90 are fixed on two straight bars 89 (Figs. 2, 1 and 7) whereof one is before and the other behind the warps and said bars are supported on each side of the machine inside of the frame by arms 91 pivoted on pins 92 of cross heads 96 and are guided by means of fric tion rollers 93 attached to said arms which roll within the curves 9-1 of guide pieces 95 fixed to the frames.

Each cross head 96 is seated on the top of a rod 97 (Figs. 1, 3 and 1) ,whichis adapted to slide up and down within a guide piece 98 fast to the frame. This movement is caused by an angular lever 100, 101, which engages by a slot in one of its arms a journaled roller 99 provided on the said rod and further engages by a friction roller fitted to its other arm a groove within the said face of a disk 3 on the driving shaft 2 (Figs. 1, 2, 1 and 6). Thus guide plates 90 may be easily brought into the upper positions as indicated in Figs. 1, and 5, in order to support the shuttle or into a. lower position as indicated by Fig. 6, in order to be withdrawn from the path of the shuttle. Owing to the shape of curves 91 said shuttle guide plates 90 are brought nearer together or moved apart according to need. As shown in F ig.'5, these guide plates form the lower, the warp w and 00 the lateral, and reed 23 the upper guides for the shuttle 37.

I As shown in Figs. 2, 3 and 7, the shuttle is received on both sides of the opened shed by the extension boxes 102 (Figs. '2, 3 and 7) of the shuttle box 36. As soon as the shuttles have left the shed a, w the guide plates 90 drop into the position shown in Fig. 6, whereupon the filling will be beaten up against the finished carpet.

The manner of working aimed at by the invention is now as follows: While the machine by means not shown is introducing at the point 1 of the warp a row of knots the reed 23 will be in the position shown in Fig. 16 while the heddles 39 and the guide plates 90 are in the position shown in Fig.6, and the shuttle- 37 is ready to be thrown from ions 45, 47, on the shaft 46, and the toothed disk 52, and then the reed and guide bars are returned to the positions shown in Figs. 1, 4, 5 and 13 by the link 6 and the parts associated therewith as .hereinbefore described. Simultaneously the guide plates 90- have been moved from the position shown in Fig. 6 1nto the position shown 1n F 1g. 4 by means of the cam disk 3. The picking stick.

59 will therefore strike in the direction'of I the arrow, Fig. 3 and will send the shuttle through the opened shed. (Fig. 7) into the opposite shuttle box whereby the woof thread a on the spool 38 will unwind. As soon as the shuttle 37 has passed the guide plates 90 these latter will drop again into the position shown in Fig. 6 and the reed 23, owing to the action of the cam disk ,3, will move to beat up the filling z at the point 3 of the warp. Simultaneously the heddles 39 will move from the position shown in'Fig. at into that shown in Fig. 5, and will cross the warps above the woof thread just shot in. The reed'23 and the guides 90 now rise and the shuttle 37 is then thrown back again into the starting shuttle box. thread a is again beaten up at the point u of the warp in the same way as explained above and the whole process will be repeated until another row of knots has been introduced. The woof thread however may also be shot in without employing the lower guiding means, as hereinbefore described. This may be done by the mechanism represented in Figs. 10, 11, and 12. The shuttle 37 then has a cross section, as illustrated at 103, in Fig. 10, so that it almost fills upthe opened shed 02, m Shuttle boX36 and its extension 102 and also the shuttle driver 58 will then have to be modified in form accordingly, but the working remains the same as shown and described for the preferred form illustrated in Figs. 1 to 7.
